When enabled you can set how low of a resolution it can go to based on a percentage of your current resolution.

There is some performance gain from this and could be worth to use when you are GPU bound. Radeon Boost is an algorithm that reduces the resolution dynamically when its not noticed* (during fast movement from player input). If you do, and it annoys you, try setting a higher minimum FPS. You might notice a bit of a stutter when you quickly go from the minimum to the maximum FPS limits you set. It can be helpful for gaming laptops, to help keep thermals in check. For desktops playing Planetside 2, this is not needed. Set the Minimum FPS to the lowest acceptable FPS for you during idle gameplay. Set the Max FPS to the highest FPS that you'll ever need in the game. This feature can not be used simultaneously as Anti-Lag, so when looking for performance I would not use this.

It automatically adjusts your frame rate within the set range to save power when its not needed. Radeon Chill is an FPS limiting function meant to save power, which means less heat or noise from your computer. I am unsure if this feature shares the same downsides as Nvidia's Low Latency Ultra mode when not being GPU bound. This setting can be enabled to lessen input lag. Pacing this better results in less input lag - which is what Anti-Lag attempts to do. Usually games are GPU bound, where the CPU is working at least one frame ahead of the GPU. Radeon Anti-Lag is a feature intended to reduce input lag in the driver stage.
